Technical Specifications of TOPA Hydraulic Units

1. Unit Models and Operating Parameters

The document provides detailed specifications for six TOPA hydraulic units: 300F, 500F, 1000F, 1200F, 1500F, and 2500F. Key operating parameters include:

• Operating Weight (ton): Ranges from 3-5 tons (TOPA 300F) up to 24-32 tons (TOPA 2500F).
• Overall Length (mm): Varies from 700 mm (TOPA 300F) to 1300 mm (TOPA 2500F).
• Operating Oil Pressure (bar): Increases progressively from 100-130 bar (TOPA 300F) to 160-185 bar (TOPA 2500F).
• Oil Flow (l/min): Ranges from 30-60 l/min (TOPA 300F) to 160-200 l/min (TOPA 2500F).
• Blow Frequency (bpm): Decreases from 500-900 bpm (TOPA 300F) to 300-450 bpm (TOPA 2500F).
• Chisel Diameter (Ø mm): Increases from 68 mm to 150 mm across models.

2. Impact Energy and Torque

• Impact Energy (Joules): Ranges from 836 J (TOPA 300F) to 5878 J (TOPA 2500F).
• Torque (ft•lb): Varies from 617 ft•lb to 4335 ft•lb, increasing with unit size.

3. Additional Dimensions (mm)

Dimensions labeled A through I are provided for each model, indicating various component lengths and sizes. For example:

• TOPA 300F: A=145, B=192, C=139, D=337, E=399, F=928, G=426, H=1301
• TOPA 2500F: A=280, B=310, C=287, D=565, E=735, F=1587, G=920, H=2507, I=469

4. Performance Ranges

• Impact Energy Range (ton): From 0.15-0.30 tons (TOPA 300F) up to 0.9-1.25 tons (TOPA 2500F).

Summary of Critical Information

• The units are designed for excavators with operating weights from 3 to 32 tons.
• Operating oil pressure and flow increase with unit size to deliver higher impact energy and torque.
• Chisel diameter and overall length scale with unit capacity.
• Blow frequency decreases as unit size and impact energy increase, indicating a trade-off between power and speed.

This structured data supports selection and application of TOPA hydraulic units based on excavator size and required performance.
